Costs of Automobile Air Emissions in U.S. Metropolitan Areas

Automobile air emissions are a well-recognized problem and have been subject to considerable regulation. An increasing concern for greenhouse gas emissions draws additional considerations to the externalities of personal vehicle travel. This paper provides estimates of the costs for automobile air emissions for 86 U.S. metropolitan areas based on county-specific external air emission morbidity, mortality, …

Trillion-frame-per-second video

By using optical equipment in a totally unexpected way, MIT researchers have created an imaging system that makes light look slow. MIT researchers have created a new imaging system that can acquire visual data at a rate of one trillion exposures per second. That’s fast enough to produce a slow-motion video of a burst of …

Higgs and Mach Effect

James Woodward view on Higgs We now know that at cosmic scale space is flat, so critical cosmic matter density obtains. That means that phi [the total scalar gravitational potential] equals c^2. So, in Einstein’s second law c^2 can be replaced by phi, and now m * phi = E. It takes no genius to …

Making a light-harvesting antenna from scratch

A biomimetic antenna for gathering sunlight may one day transform solar-powered devices. At Washington University in St. Louis’s Photosynthetic Antenna Research Center (PARC) scientists are exploring native biological photosystems, building hybrids that combine natural and synthetic parts, and building fully synthetic analogs of natural systems. One team has just succeeded in making a crucial photosystem …

3D printer used to make bone-like material

Washington State University researchers have used a 3D printer to create a bone-like material and structure that can be used in orthopedic procedures, dental work and to deliver medicine for treating osteoporosis. Paired with actual bone, it acts as a scaffold for new bone to grow on and ultimately dissolves with no apparent ill effects. …

External costs fossil fuels, hydro, and nuclear

Many times in energy discussions there are claims about nuclear power having vulnerability to terrorism or other intentional damage and to the cost of nuclear power damage from other disasters (Japan tsunami and earthquake) or by nuclear power accidents (Chernobyl). Other energy also have high damage potential. The Teton Dam was a federally built earthen …
